Transition plate structure suitable for independent teleoperation of first wall of divertor

Abstract

The invention discloses a transition plate structure suitable for independent teleoperation of a first wall of a divertor. The transition plate structure is formed by welding a protective armor and asupport plate; tungsten is used as a protective armor material; chromium zirconium copper is used as a support plate material; the transition plate structure is connected with a first wall support structure through two connecting bolts; a water inlet / outlet pipe of the first wall structure and divertor first wall structure connecting bolts are located on the back surface of the transition plate; amultifunctional mechanical arm can enter a vacuum chamber from an upper window and a middle window; and the transition plate is detached, and a first wall structure is independently removed or installed. According to the invention, the first wall structure of the divertor can be automatically and quickly assembled or disassembled with high precision in a nuclear-related environment; the installation precision of the first wall structure of the divertor is improved, and installation steps are simplified; the first wall structure only needs to be independently maintained through the middle window or the upper window, so material waste is reduced; and the structure has the advantages of money saving, time saving, high efficiency and high precision.

Description

technical field [0001] The invention relates to the design field of divertors of nuclear fusion reactors, and mainly relates to a transition plate structure suitable for independent remote operation of the first wall of the divertor. Background technique [0002] Energy shortage and environmental pollution are two major problems facing mankind today. At present, fossil fuels are the main energy sources for human production and life. However, with the increase in global energy consumption and unscientific use, non-renewable energy sources such as fossil fuels will be increasingly exhausted, and will have a serious impact on the environment, causing serious pollution to the environment. This urgently requires people to develop hydrogen energy and nuclear energy. , wind energy, geothermal energy, solar energy and tidal energy and other new energy sources. The utilization and development of these energy sources can not only partially solve the crisis of fossil energy depletion,...

AI Technical Summary

Problems solved by technology

Therefore, for the overall remote operation maintenance scheme of the current nuclear fusion reactor divertor, its maintenance period is very long, but for the nuclear fusion reactor divertor components, most of the damage events occur on the first wall, and because the divertor will be damaged Radiation activation and contamination by tritium are harmful to humans, so that humans cannot directly contact them, so other divertor components that have been replaced with good functions cannot be reused, and the disposal of decommissioned components is also a major problem, so the use of The overall remote operation and maintenance of divertor components will inevitably cause unnecessary waste of resources
